A shoe includes a sole member, at least one heel member, a front securing member, and optionally a forward tread member. Each heel member includes a column portion having a predetermined height and a blade portion having a predetermined slope. Each blade portion's slope corresponds to the respective column portion's height for providing a proper amount of arch support for a user's foot. The sole member has an arch region made of a flexible material that defines a sleeve for selectively receiving each respective blade portion. Each blade portion includes a flange extending longitudinally therealong, and the sleeve defines a complementary groove. When the sleeve receives a respective blade portion, the blade portion provides shape and structural support for the sole member. Means for releasably attaching the respective column portion to the sole member are utilized, and the front securing member may secure the sole member to the user's foot.
